Experimental Study of Optimal Erection Schedule of Prestressed Concrete Bridge Girders
A high performance concrete (HPC) bridge was instrumented for short-term and long-term behaviors of prestressed beams. The bridge is a twin-bridge over Pistol Creek in Blount County, Tennessee. The beams in one bridge lane were of high strength concrete (HSC) with a specified compressive strength of 10,000 psi and the ones in the other lane were of normal strength concrete (NSC) with a specified compressive strength of 6,000 psi. The primary objectives of the research were to experimentally study the time-dependent behaviors of HSC and NSC bridge beams and cast-in-place concrete deck and diaphragm during various stages of construction and service and to investigate the optimal erection schedule for HSC bridge beams. The selected bridge was instrumented for measurements of concrete temperature, strains of prestressed beams during curing and other stages. Material properties of both concretes were obtained through laboratory tests. A live load test was conducted for the evaluation of distribution factors of love load moment.
